That is way too hot, where were you measuring oil temperature?

While I understand your valid point that it is too hot, I believe the term "overheating" was used here meaning when you see the temperature gauge in the car go to H and need to stop using it.

Also, synthetic oil is not expected to break up at those temperatures. But I do agree with you, I don't want those temperatures in my car, but then I also don't plan on tracking my car more than a few times a year. I got some heat mitigating parts on the way.

Anyone going try out the Perrin CAI? Still wondering if itll work.

Overheating can apply to anything really. 135-140c is too high, the oil no matter what it is will thin out and you'll be running very little oil pressure which isn't good. If you are hitting like 125-130c+ I'd be looking at an oil cooler.

Me I don't see why it wouldn't, fits right with the stock tube which is the exact location AVO uses. You'll have you anwser by next weekend.

Yes, I agree 100% with all your points.

80 laps in one day - trust me, we were not expecting the oil to run cool! This was a stress test, we wanted to see what the oil and water temps would be like with no external coolers while running the turbo kit flat out.

As mentioned previously, we do suggest running an oil cooler if you are going to circuit race with the kit, but to better clarify that, we would suggest to run the oil cooler, period, if you are going to be doing a lot of circuit racing, n/a or turbocharged. Even the n/a's will be running quite hot. And when you make more hp, you have more heat in the engine. A 250whp n/a setup will run hotter than a 170whp n/a setup.

I think im going to start piecing stuff together.

7 psi aculator
AFR/Boost/oil temp gauges
Fuel pump/injectors
3 bar Map sensor
Catch can

Hopefully that will let me run 10-11psi on 93.

I have oil temp gauge for sale right now (Price negotiable) and yes, the fuel pump injectors will allow you to run 11 psi on 93

which cc' injectors?

and which fuel pump are you looking for?

I'd love to reach 13-14 psi on 93

I'm not going to buy now, but did some research and the injectors I believe are best are the 550cc from Visconti. For fuel pump I'm still waiting for something more "drop in" than the current offerings.

Ill think about the gauge but im still trying to find a way to mount the 3 gauges without it looking ridiculous and blocking stuff.

You only need two. AFR/Boost can be had in one gauge. AEM Failsafe.

I can still improve on these numbers by getting the boost up to spec, especially in the torque department.

I kinda like that lol. It must feel like v-tec kicked in yo.

In fantasy land I'd like to keep boost even untill 6500 rpms when the VE starts to drop. That is where I would adjust the EBC to increase boost to keep torque flat.

You don't need an EBC to keep a flat boost curve. Dropping boost with revs is often a sign of a turbocharger of less-than-ideal spec for the application.

That boost curve above is just weird. I can only assume there's an EBC hooked up, or the OE ECU is doing some boost control, badly.

But as you say, vubaru, you intend to get this sorted. I'm sure it'll be great after that's done.

What kosh was referring to was not keeping a flat boost curve, it was manipulating the boost to keep the torque curve flat.
